Hesitant to announce an opening date for the new Central Middle School in Wollaston, city leaders are saying only that the school should open sometime this fall.

Construction crews are still putting the finishing touches on the new three-story school, which was initially supposed to open last week for the first day of school. However, Central Middle School students started the year at the old facility at 1012 Hancock St. after city officials decided the new building wasn’t ready for students.

Mayor Thomas Koch met with project leaders Wednesday to get an update on the $50 million school building project.

“They’re pushing ahead, but it’s the status quo,” Christopher Walker, spokesman for Koch, said. “The mayor and the (school) superintendent are not going to rush into this building.”

Laura Owens, executive assistant to School Superintendent Richard DeCristofaro said no opening date for the new school has been set. Walker said the opening would take place before the end of fall.

Walker said crews are still building the auditorium and moving in school equipment.
